Exclamation [Q] Unable to boot phone from "charge screen"

Hi XDA,

I got this weird problem. Not 100% sure if its by design. But i seem to remember it not beeing like this with past firmwares.

On my HTC One M7
With any of the later firmwares. (Havent tested the older ones) i cant boot the phone from the "charging screen" I have to hold down the power button for around 10 seconds, until the phone powers down. And then i can boot it up.

Anyone know whats going on?
HTC One M7UL
